The Darex Story
The Darex Story
Darex Corporation began in 1973 in Beecher, Illinois. The D, A and R of Darex are the initials of three generations of the Bernard family; David, Arthur and Richard Bernard. David and his father Richard founded Darex. Grandfather Arthur Bernard, who earlier founded the Bernard Welding Company, contributed his energy and guidance to Darex. Art’s inventions revolutionized the welding industry.
In 1978, Darex relocated to Ashland, Oregon. Grandson Dave and son Dick carry on Arthur’s legacy of inventiveness. Darex grew to become the most recognized name in the cutting tool sharpening industry. Today, Darex is a world-leading manufacturer of precision cutting tool sharpeners.
Darex is proud to offer a complete line of quality precision cutting tool sharpeners at affordable prices. Before our first days, we at Darex had looked at our competitor’s sharpeners and asked ourselves: “Must cutting tool sharpeners be complicated? Why must the choice be limited to cost prohibitive accuracy or low price inaccuracy?” Our sharpeners prove you can have it all: Simplicity, Accuracy, and Affordability.
We have always emphasized innovative product design and tested technology. The experienced personnel at our modern manufacturing facility use the latest production methods. The Darex marketing team knows first-hand the machines we sell and will guide you to the best machine for your needs. Our skilled technical service department is happy to answer your questions about our products or cutting tools.
The XPS-16 CNC Sharpener
The Darex XPS-16 CNC Drill Sharpener can be programmed to sharpen an infinite variety of conical, four-facet, split-point and/or radius split point drills. The XPS-16 can sharpen HSS and carbide twist drills from 1/8” to 5/8” (3- 16 mm) diameter, 2” to 8 ¾” long, and angles of 90 to 150 degrees. Memory stores user-defined drill point geometries. In a single set-up the Darex XPS-16 automatically sizes, aligns, then sharpens the drill and splits the point and can hone the drill’s cutting edges to minimize chipping. Benefits include: Convenient internal chuck holds drill; LCD screen display panel for one-touch programming; Long-lasting super-abrasive plated grinding wheels; “Grind Motion Control” monitors load on the grinding wheel; adjusts feed and speeds keeping drills cool, diagnostic software alerts operators of potential problems.
To keep your Darex XPS-16 in top condition, please refer to the maintenance section of this manual. Replacement wheels and parts are listed in the parts list on page 83 & 84. A schematic breakdown of the machine is on page 85 of the manual.

Safety Instructions
Safety Instructions
GROUNDING INSTRUCTIONS
•For all grounded, cord connected tools:
•In the event of a malfunction or breakdown, grounding provides a path of least resistance for electric current to reduce the risk of electric shock. This tool is equipped with an electric cord having an equipment-grounding conductor and a grounding plug. The plug must be plugged into a matching outlet that is properly installed and grounded in accordance with all local codes and ordinances. Do not modify the plug provided-if it will not fit the outlet, have the proper outlet installed by a qualified electrician. Improper connection of the equipment-grounding conductor can result in a risk of electric shock. The conductor with insulation, having an outer surface that is green with or without yellow stripes, is the equipment-grounding conductor. If repair or replacement of the electric cord or plug is necessary, do not connect the equipment-grounding conductor to a live terminal. Check with a qualified electrician or serviceman if the grounding instructions are not completely understood, or if in doubt as to whether the tool is properly grounded. Use only 3-wire extension cords that have 3-prong grounding plugs and 3-pole receptacles that accept the tool’s plug. Repair or replace damaged or worn cord immediately. See Table 1. Minimum Gauge Cords below.
•Grounded, cord-connected tools intended for use on a supply circuit having a nominal rating less than 150 volts:
This tool is intended for use on a circuit that has an outlet that looks like the one illustrated in Figure A. The tool has a grounding plug that looks like the plug illustrated in Figure A. A temporary adapter which looks like the adapter illustrated in Figures B and C, may be used (except in Canada) to connect this plug to a 2-pole receptacle as shown in Figure B if a properly grounded outlet is not available. The temporary adapter should be used only until a qualified electrician can install a properly grounded outlet. The green colored rigid ear lug, etc. extending from the adapter must be connected to a permanent ground such as a properly grounded outlet box. See Fig. 1. Grounding methods below.
•Grounded cord-connected tools intended for use on a supply circuit having a nominal rating between 150-250 volts inclusive: See Table 1. Minimum Gauge Cords below.

XPS-16 Auto Measurement Features
Your XPS-16 has many features so carefully designed and engineered that you may not even be aware of their uniqueness. Once the cycle start button has been pushed, your Darex XPS-16 begins taking measurements of the drill, on the way to the grinding wheel. Your XPS-16 locates the end of the drill, calculates diameter, locates and positions the cutting edge, determines web thickness, identifies initial contact point of drill to the wheel and then sharpens. After sharpening and before splitting the drill, your XPS-16 sharpener again measures and re-locates the end of the drill, ensuring an accurate split.

Touch Screen Details
Hone Selector
•With each touch of the icon you will bring up the next honing option. You have 3
options: Hone, No Hone or Hone Only
NOTE: Factory default is “NO HONE”.
•Select “HONE” when sharpening carbide drills. Honing the carbide cutting edge greatly influences tool life and the accuracy of the finished surface. The length of hone time is adjustable. The longer the
drills cutting edge remains in the honing cycle, the larger the radius produced on the cutting edge. Refer to page 53. Go to the Hone Timing Adjustment Screen in the Tools, Maintenance and Offset screen to make honing time adjustments. Refer to page 31
•Select “NO HONE” when sharpening High Speed Steel or Cobalt drills.
•Select “HONE ONLY” when only honing drills. Grinding and Splitting will be disabled.
Grind Selector
•With each touch of the button you will bring up the next point style option. There are 2 point
style options: Conic or Facet
NOTE: Factory default is “CONIC”.
•“CONIC” – This radial/cone style grind is known as a conventional point and used through out the machine tool industry. A lip clearance of 12° to 15° at the periphery of the drill, increasing constantly toward the center, is considered standard for the average
class of work.
•“FACET” – Multi faceted drill points consist of a separate cutting lip (primary)
and secondary heel clearance (relief) facet. The multi-faceted drill requires 150% less thrust and produces 70% less heat than a conventional drill.
•The width of the primary facet is determined by the thickness of the drills web and cannot be changed. If your drill has a thin web, we do not recommend a facet point style. The width

Split Point Selector
•With each touch of the icon you will bring up the next split style option. There are
3 split point options: No Split, X- split (Standard) and R- Split. (Radius) The XPS-16 will produce a chisel angle ground to approximately 130°.
NOTE: Factory default is “SPLIT”.
•“NO SPLIT” – Select when reproducing a non-split drill point style.
•“X-SPLIT” – 4° split point rake angle is created, producing a drill with a selfcentering point. Its advantages are the ability to reduce thrust and eliminate walking at the drill point. This is a distinct advantage where drilling bushings/fixtures are not used.
•“R-SPLIT” – The R-split selection is not an option until the web thickness value has been manually entered. Changing the amount of radius and rotation is adjustable. This is done in the Split Point Offset screen . Refer to information on page 35 for details.
•An R-split will produce a drill with a selfcentering point as well as act as a chip breaker producing smaller chips, which can readily be ejected. The radius will assist the flow of chips and reduce chip impaction at the tip of the drill.
Relief Screen Selector
•Select lip relief clearance from 5° to 18° +/-2°. The diameter and the point angle will determine the degrees of
possible relief. See tables below.
NOTE: The degree of relief entered, will appear on the relief selector button on the main screen menu.
